GLASS SHINGLE.

SPECIFICATION formingpart of Letters Patent No. 734,976, dated July 28,1903. Application filed May 21, 1903. Serial No. 158,177. (No model.)

T0 (0 whom it may concern.-

Be it known that I, JACOB SIMMERMAN, a citizen of the United States,residing at Dunkirk, in the county of Jay and State of Indiana, haveinvented a new and useful Improvement in Glass Shingles, of which thefollowing is a specification.

My invention relates to shingles, and has for its objects to produce adevice of this character which will be simple of construction, efficientin operation, one in which the shingles when assembled upon a roof willbe securely interlocked one with another, and one by which strength anddurability are obtained and liability of the shingles decaying andholding dampness is obviated.

To these ends the invention comprises the novel details of constructionand combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective viewillustrating the manner of assemblingthe shingles constructed inaccordance with my invention. Fig. 2 is a vertical transverse sectiontaken through a pair of shingles assembled.

Referring to the drawings, 1 indicates a shingle which in accordancewith my invention is provided upon the upper half of its lower face withtwo rectangular depressions or recesses 2 3, which are divided by acentral longitudinal depending flange or rib 4, are bounded upon theirouter sides by longitudinal depending side flanges 5, and at their upperends by a transverse depending end flange 6, said recesses terminatingat their inner ends in abrupt transverse shoulders 7 The shingle isprovided upon the lower half of its upper face with a pair ofrectangular elevated portions or projections 8 9, which are divided orspaced apart by a central longitudinal recess or gutter 10, are boundedupon their outer sides by longitudinal side depressions 11, at theirlower ends by a transverse depression 12, and at their inner upper endsby a transverse recess or gutter 13.

14 indicates countersunk perforati ons which are formed through theshingle at suitable points in its lower half for the reception of nails,by which the shingles are in practice secured to the roof-framework.

In practice the shingles half overlap one with another and when a pairof the shingles are assembled the projections S 9 fit into and By thisconstruction it will beseen that the shingles when assembled aresecurely interlocked one with another and that danger of them becomingloosened and falling from the roof is entirely obviated, while at thesame time the shingles may in practice be very rapidly assembled.

My improved shingle, as above constructed, is preferably composed ofglass, which material is highly adaptable for the purpose and produces ashingle which is strong and durable, one which will be a non-conductorof both heat and lightning, one which is admirably adapted for use inconstructing skylights, and one which during its manufacture may bereadily colored or tinted, as desired.

In manufacturing my improved shingle I cast or press the same in moldsin a manner which is well known in glass manufacturing;

Having thus described my invention, What I claim is 1. A shingleprovided upon the upper half of its lower face with a pair ofdepressions divided by a depending central flange and bounded bylongitudinal side flanges, an outer transverse end flange and an innershoulder, and upon the lower half of its upper face with a pair ofprojections divided by a central longitudinal recess or gutter andbounded by longitudinal side depressions, an outer transverse enddepression, and an inner transverse recess or gutter.
